Stuart Locomotive

251 G.N.R.

The above is an illustration of one of the latest G.N.R. Atlantic type of Ten Wheelers with a Wootten Fire-Box; and on the preceeding page is a general view of a 3in. scale Working Model.

The cylinders are 1 in. by 1 1/2 in. stroke. The bogie wheels in the model are made slightly smaller than scale to allow them to pass under the engine frame ‘when on a curve, but standard scale wheels can be used to obtain a correct model. This is built for a 38 gauge, but can be varied slightly.

The main framing stops at the firebox, and is continued outside the bogie wheels, thus allowing ample room for the burner. This is done by means of castings, on which are cast the axle-box horn-plates and dummy laminated springs. A hairpin type of super heater is used. A large valve chest common to both cylinders, fitted with a large door, by means of which the setting of valves is a simple matter. Link reversing gear is fitted. The smoke-box door is cast in one piece and can be removed intact, thus allowing ample room for any adjustment inside.

The firebox end and tube plate is cast of best gunmetal, with flanges, and a single sheet of copper riveted round this forms a very reliable and also simple method of construction,A cast throat plate and firebox shell end is also used.

The castings include all cast parts in iron, steel, and gunmetal, of the finest quality.

The plate work and tubes consist of all materials necessary to construct this model, with the exception of brass fittings, such as guages, cocks, etc., and screws and rivets.

Every model maker knows the trouble of obtaining the odds and ends required to complete a loco after he has stings. To obviate this I have (as in the L.N.W. set) carefully supplied every piece necessary. A very liberal allowance of material is supplied of the very best quality obtainable. All steel plates are carefully machine-cut to overall dimensions and are perfectly clean, flat, and free from twist. The total length of engine and tender is 3 ft. 7 in.

The castings of this loco, are suitable for many other types of outside cylinder engines, such as the N.E.R. "Atlantic".

The "Model Engineer". February 9th, 1905, in referring to the recent exhibition at Holborn Town Hall, says: "Stuart Turner's show of High Speed Engines and Engine Castings was much appreciated, all sizes of his famous engines being represented, from the small T.B.D. engine to the 6 h.p. Compound Launch Engine. On his stand was a very fine model of G.N.R. 251, which he has lately completed to the order of a customer."

A nice looking 4-4-2 engine with outboard cylinders and a tender. As i am not a Locomotive expert there is little more for me to say other than it looks just like the real thing see below.
